WNS condensing gas-fired steam boiler adopts horizontal internal combustion wet-back type structure. External pressure energy-saving condenser, condenser material is ND steel with good corrosion resistance. Condensing gas boiler for sale adopts fully threaded finned tube structure to increase the heat receiving area and significantly improve the thermal efficiency. Under the condition of condensing sensible heat, the thermal efficiency can reach more than 97%, which can save fuel cost significantly for users.
This series of WNS gas steam boilers, tempering combustion chamber and rear tube plate docking, boiler using all butt welding, more reliable quality. The boiler combustion chamber is composed of large-diameter full corrugated furnace, with large combustion space, complete fuel combustion, effective heat absorption and expansion, and large radiation heating surface. In order to improve the thermal efficiency, this type of boiler is equipped with energy-saving devices and condenser in turn at the exit of the front flue box, with remarkable energy-saving effect.
Condensing gas boiler for sale has high and low water level alarm function, low water level interlock protection function and overpressure interlock protection function. In order to effectively monitor and control the water level and pressure of the boiler, it is equipped with water level meter, electrode type water level control and alarm, and also equipped with pressure gauge and pressure controller, so that the boiler has high and low water level alarm and interlock protection and steam pressure low water level overpressure interlock protection, automatic ignition of the boiler, automatic adjustment of burner fire and flame out protection to ensure safe operation of the boiler.
The fuel of this series condensing boiler is ejected from the burner, ignited by high pressure electronic ignition and burned in the furnace chamber under micro positive pressure. After combustion, the high temperature flue gas is turned 180° from the rear flue chamber into the second return. From the front flue box it turns 180° into the energy saver and condenser and is discharged into the atmosphere through the chimney. The front flue box is equipped with integral double doors and the flue box doors are double sealed. The pot is integral, beautiful, generous and light to open during maintenance. The height of the chimney is configured at the factory. Users should determine the actual height according to the requirements of the environmental impact report approved by the local environmental protection department, but not less than 8 meters.
Condensing gas boiler for sale have good steam quality, large shell diameter, large water capacity, adaptable to load changes, and stable output. The steam space volume is large, the net distance between steam and water interface and steam outlet is large enough, and the steam humidity is low. ZOZEN Boiler is exported to many countries in the world and have been well received and trusted by our customers. We can also customize the boiler drawings provided by customers on a one-to-one basis according to their needs. We welcome customers to consult and purchase.
